Applications > Coating
We would like to present you a selection of our switch cabinet engineering and control technology in the field of coating machinery:
PVC and acrylate coating
This plastic coating system was completely overhauled by us electrically.
The drive technology and PLC control system were fully replaced, where the drive engineering mixture of servo and DC drive were equipped with new hardware and software. A new drive concept was also implemented. All control technology tasks are carried out by S7 software. Furthermore, a new visualisation was installed with WinCC as a multimonitor solution.
A networked service PC in an air-conditioned control cabinet room provides maintenance and recipe management via Access. With these measures, a higher level of production speed has now been achieved, which means that this conversion has paid off within a short period of time.

This coating line with subsequent embossing roller produces in several different modes. The various processes demand different combinations of the use of the previous and subsequent parts of the plant.
The new drive technology follows these demands and reduced start-up times for production. The necessary temperatures (thermal oil heating and infrared emitters) are controlled by software controllers.
PVC and acrylate coating
Mehler Texnologies Fulda
This new 5.40 m wide coating line processes PVC and acrylate coating.
The visualization and the S7 PLC represent the central control of the plant. The individual operating panels on the plant are networked by Profibus. Via the various operating panels the associated parts of the plant are locally controlled.
The settings made by the operator on the local operating panels are recorded and saved by the central visualization. Likewise, the complete drive technology is networked with Profibus. The speed and torque of the line drives is controlled by dancers and load cells. The two stenter chains are connected by a electrical shaft to maximize synchronous accuracy.
The accumulator at the inlet and the outlet of the plant allow continuous production. Farbric tension at the two rewinders is controlled by the drives torque control and is adjusted according to the actual diameter. Furthermore, the speed of the several ventilators, the positions of the blades and the temperatures are connected by Profibus and controlled by the PLC.
This systematic implementation of modern technology lead to a service-friendly control system.
